EMPTY-PAGE(1)							 ExactImage Manual						     EMPTY-PAGE(1)

NAME
empty-page - empty page detector of the ExactImage toolkit SYNOPSIS
empty-page [option...] {-i | --input} input-file empty-page {-h | --help} DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit depths natively, resulting in low memory and computational requirements. empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can be removed from the image processing stream. OPTIONS
-i file, --input file Read image from the specified file. -m n, --margin n Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16. -p x, --percentage x Set fraction of permissible dark pixels. The default is 0.05 (5%). -h, --help Display help text and exit. EXAMPLES
$ empty-page -i test.tif The image has 75461 dark pixels from a total of 1060992 (7.11231%). non-empty EXIT STATUS
The exit status is 0 if the image is mostly white, 1 otherwise. SEE ALSO
